The Villa defender insists he and the rest of his side are only looking forward as they endeavour to improve their poor run of form.
The game was locked at 0-0 at Stamford Bridge before Joleon Lescott miscontrolled a heavy pass from keeper Brad Guzan to allow Willian to play Diego Costa in for the opening goal
That set the champions on their way to an eventual 2-0 victory, and Richards admits that the mistake deflated Villa, but says respect must be paid to Chelsea for their display.
“In the second half we didn’t come out as well as the first,” he told BBC Sport.
“The first goal killed us, because before then we were on top. If you’d wondered who was Villa and who was Chelsea in the first 30 minutes, you'd have said we were Chelsea. But you have to respect Chelsea - they are a top team for a reason.”
Aston Villa only looking forwards
The Villans captain has also insisted that the side will not be dwelling on this performance as they try to end their current poor run of form.
Tim Sherwood’s side are currently 18th in the Premier League table with a measly four points to their name, and as a result find themselves four points from Bournemouth in 17th ahead of them,
It is easy to imagine that confidence is low around Villa Park, with rumours that Sherwood could lose his job also unlikely to be helping, but Richards insists that isn’t the case and instead they are only forward with confidence.
"We won’t dwell on this - we have a tough game next week, but it's at home and it's one we'll look to win,” he added.
"Throughout this season there haven’t been many games we've deserved to lose. But we'll roll on. The confidence is not low, no matter the results at the moment. The manager has been great and we are only looking forward."
